Oconnell · Answer 1

C.

Explanation:

Recessive disorder linkage study is the analysis of genetic diseases inherited. Large population of affected members are used in this type of linkage analysis because they have a known genotypes to work with in order to avoid false-positive result in the study

Kenneth Kramer · Answer 2

Answer: B. They have carrier parents

Explanation:

A recessive gene occurs in person when the person has inherited the same two alleles for gene, one from each of the parents. Due to the fact that the alleles are similar it is also know as homozygosity.

A recessive gene could lead to disorders in a person. Examples of recessive disorders are: Sickle cell anaemia, Albinism, Cystic fibrosis e. t. c.

Recessive disorder linkages are primarily studied because the parents of the individual who has a recessive gene disorder are carriers of that same gene.
